Preheat oven to 350ºF
Grease a 10x15 or 9x13 baking dish
In a large bowl combine the eggs, sugar, pumpkin, and oil. Mix until smooth.
In a separate bowl combine the flour, baking powder, cinnamon, baking soda, salt, cloves, ginger, and nutmeg. Using a large whisk, mix these ingredients thoroughly until all large lumps disappear.
Add flour mixture to the liquid ingredients. Stir until thoroughly combined and all the white color from the flour is gone.
Spread evenly in the prepared baking dish.
Cook for approximately 30-35 minutes. Test cake doneness with a toothpick entered into the center of the cake. When removed, if the toothpick is clean, the cake is done.
Allow the cake to cool completely before frosting.
